SPECIFICATION forming part of Letters Patent No. 753,488, dated Maren I, 1904.

' mingham, in the county of Jefferson and State ssl ` Likenumerals of .reference are employed to,

of Alabama, khave invented a new and 1useful' Cotton Gin and Condenser, of which thefolflowing is a specication.

This-invention relates to a combined cotton `gin and condenser, and has for its object to vprovide-a simple machine involving an inexpensive construction and an economical expenditure of power and capable of effecting the complete gining o r delinting of the ordinary or shortv-staplecotton-seed andthe simultaneous condensingaof the cotton, so that the latter will be fed from the gin in the formv ganize the ginning mechanism that the staple or fiber will not be broken, butwill be removed from the seeds and fed from the gin in natural lengths. y

Further objects of the invention are the provision of .ginning blades or saws any one of which may be readily removed and replaced without disturbing the others in the case of derangement or mutilation and the provision of a novel and readily-adjustable automaticv feeder for feeding the seed-cotton to the ginning apparatus at a speed corresponding to that at which the gin is operated.

In addition to these objects are others subordinate thereto, as will appear during the course of the succeeding' description of the illustrated embodiment of the invention.v v

In the accompanying drawings, Figure 1 is a side elevation of my combined gin vand con-v A of the delinting. blades Vor saws,'and Fig. 5 is a transversesection thereof. Fig. 6 is a sectional view on-the line y(i 6 of Fig. t, showing the undercut biting edges or projections on the front Yface of the blade.

Application filed August 28, 1902.- Serial No. 1,2I,366'. (No inodel.)

designate corresponding parts throughout the views.

The frame of the machine comprises a pair of standards l and 2, connected by horizontal beamsV 3 and 4:, and a table 5, having side beams 6, connected at their rear ends to the standards l and 2 and supported at their front ends by suitable supports 7.

The most distinctive feature of the apparatus considered as a departure from usual gin constructions is a reciprocating blade or saw frame .8, engaging suitable guide-grooves 9 in the opposed faces of the standards l and 2 and carrying a series of vertically-'disposed delinting blades or sawslO. The saw-frame 8 is of openform vvand comprises at its lower end a transverse slat l1, against which the at shanks l2 of the saws 10 are clamped by a pair of clamping-strips 13 and 14, screwed to the slat 11. This character of retaining means permits the ready removal of any individual saw in the levent of its mutilation or derangement without necessitating the removal of the remaining saws of the series, this latter feature being of considerable importance, since it is well understood by those skilled in the art that the replacement of a saw in ordinary forms of gins is accomplished only by the disorganization of the entire gang of saws associated with the injured member. The saws or blades 10 are of peculiar construction. Asshown more clearly in Fig. 2, they are disposed edge to edge with an interval sufficiently small to prevent the passage of cotton-seeds between them, and their edges are formed with downwardly-pointing teeth 15, the under edges 16 of which are extended lupon the front face of the saw and are undercut, so as to form biting edges or corrugations extending upon the front faces of the saws and constituting continuations of the lower edges of the teeth. It will therefore appear that the staple presented to the iiat front faces of the saws will be engaged, not only by the teeth of the latte-r, but also by these biting edges, which materially assist the teeth in retaining the sta- 20, through which the lint is forced as the.

saws move downwardly, each charge of cotton being retained Within thecondensing-chamber by engagement with teeth or projections 21, extending, for instance, from the front wall 18 and having a slight downward inclina tion, so that the upward or retractile movement of the saws will effect their complete disengagement from the cotton previously delivered to the chamber. The manner of producing the constricted throat 2() of the condensing-chamber is immaterial; but said throat is preferably defined between a pair of parallel horizontal metallic bars 22 and 23, having their opposite ends rigidly secured in the framework. The bar 22 at the rear side of the throat constitutes a backing for the blades, the lower ends of which never move above this bar, and the space between the front faces of the blades and the front bar 23 of the throat is sufficiently narrow to prevent the seeds from being carried down into thecondensing-chamber with the staple. As the front bar 23 of the throatis-disposed close to the front faces of the blades, I provide each of-said blades with a longitudinal rib extending along the middle of its front face and designed to prevent the teeth or biting edges of the saws from being brought into. contact with the bar 23 when the pressure of the cotton against the saws is insuiiicient to hold them back against the bar 22.

We have now seen that the device comprehends the employment of a series of reciprocatory gin saws or blades arranged to carry the cotton or staple into a narrow condensingchamber in successiveY charges, so that the action of the ginning or delinting mechanism will simultaneously effect the delinting of the c cotton-seeds and the formation of a bat which least the full width of the seriesof saws, and

having its open rear side 25 disposed in close` proximity to the saws and preferably supported by-the front bar 23 of the throat.

Immediately in front The bottom of the casing 24 is of open-work form to permit dirt carried into the casing with the cotton to be discharged and is provided with an enlarged discharge-opening 24a,

through which the cotton-seeds are delivered after having been delinted in a manner to be explained. Within this roll-casing is mounted at an eccentric point, so as to bring it nearer the saws, a feed-roller 26, mounted upon a shaft 27 and provided with projections or spikes 28.v The-shaft 27 is mounted in suitable bearings 29, carried by the frame, and is provided with. suitable power-pulleys 30 and crank-Wheels 31. The pulleys 30 are intended tobe belted to a suitable source of power, (not illustrated,) and the crank-wheels are designed to transmit motion to the saw-frame 8 through the medium of pitmen 32 and 33, connected at their upper ends to horizontally-disposed trunnions 34, projecting from the upper end of the saw-frame 8, and at their lower ends to the wrist-pins 35 of the wheels 31. It will now be observed that since the saw or blade frame derives its motion from the shaft 27, which also operates the feed-roller 26, the speed of the feeding and delinting mechanisms will be maintained in proper ratio, it being impossible to increase the speed of one without increasing the speed of the other proportionately. The seed-cotton is fedinto the roll-casingf24 through a hopper 36, opening into the upper side of the casing in rear of the feed-roller 26. Thehopper, being necessarilyof some length in order to convey cotton froman overhead feed-box 37, has its open rear side closed by wire-netting 38, stretched across the saw-frame 8 and designed to assist in the feeding of the cotton through the hopper, as will hereinafter appear.

The feed-box 37 is designed yto receive the cotton, for instance, from a pneumatic conveyer 39, and is provided with a reciprocatory slatted bottom or feed-slide 40, having rearwardly-inclined teeth 41 and arranged to be reciprocated by the pitmen 32 and 33 through the medium of links 42,` pivotally connected at their front ends to trunnions 43, extending through slats 44 in the sides of the box ,and having adjustable connection at their Vrear ends with the pitmen, as indicated at 45.

Obviously the throw or movement of the feed-slide within the feed-box may be regulated by adjusting the rear ends of the links 42 upon the pitmen, the throw being increased as the connection 45 is moved farther away from the trunnions 34, from which the pitmen swing. The slatted construction of the feed-slide will permit any debris' held by the cotton to drop through thel open bottom of the box.

At the front end of the feed-box is arranged a sliding feed-gate 46 forregulating the quantity of cotton fed out of the feed-box by each movement of the feed-slide. As cotton is fed IOO IlO

der that the inclination of the feed-box' may be varied, the latter is supported at its front end by links 48, swung from the upper end.

of the frame, and the rear end of the box is pivotally connected to the upper ends of a pair of longitudinally-adjustable supports 49.' provided at their lower ends with elongated slots 50, engaged by set-screws 5l, screwe into the sides of the table. v

The operation of the device is as follows: The inclination of the feed box 37 and the stroke of the feed-slide 40 having been properly adjusted, motion is communicated to the shaft 27 to cause the rotation of the feed-roller 26 and the reciprocation of the saw-frame and saws and of the slide 40. The seed-cotton deposited in the feed-box from the-pneumatic conveyer 39 will be fed from the front end of the box and will be carried down into the upper end of the hopper 36 by the feeding-lingers 47, projecting from the saw-frame.

The feeding of the cotton through the hopper will be assisted by the netting 38, and as the cotton is delivered to the roll-casing 24 it will be engaged by the spiked roller 26 and wound into arapidly-rotating roll. By reason of the yeccentric location of the roller within the casing the cotton will be urged against the front faces of the blades or saws, and the downward movementv of the latter Will cause them to engage the staple or lint and carryit down through the constricted throat 20 and into the condensing-chamber 17, where it will be retained, as stated. The teeth of the saws and:

the biting or delinting edges upon the front faces thereof will engage the lint, and as the latter is carried down the individual locks of cotton will be revolved to present the different sides of the irregularly-formed seeds to the saws. This action, which is both novel and effective, is increased by reason of thev fact that that side of the roll of seed-cotton next to the saws moves upwardly, carrying the seeds up along the front faces `of the descending saws and turning them over and over to insurethe complete removal of the lint. If,

however, the seeds should be carried back by the revolving roll of cotton before all of the lint has been detached, said seeds will becarried around by the roll and again presented to the saws until they are completely denuded of liber. When the seed has been completely stripped, it will cease to adhere to the roll of Vseed-cotton revolving within the roll-casing and will therefore drop through a discharge- By reason of the fact that the saws are presented iatwise to the seed-cotton and'not edgewise,

as usual, the staple will not be broken, but will be detached in natural lengths and fed into the condensing-chamber 17, from the lower end of whichit will issue at the rear side of the gin in the form of a condensed bat `ready for baling without subsequent manipulation.

It is thought that from the foregoing the construction and operation of my combined gin and condenser will be clearly apparent; but while the present embodiment ofthe invention is thought at this time to be preferable I do not wish to limit myself to the structural details defined, as, on the contrary, I reserve the right to effect such' changes, modications, and variations of the illustrated structure as may be properly embraced Withinthe scope of the protection prayed.
